hello i have an 88 camaro 305 and i am in need of a crankshaft with the 1 peice rear main seal....i live in delaware and am looking for one thats usable

 

FYI, i believe 305 and 350's share the same crank.... the cylinder bore separates the two? could be wrong?

 

different balancing...but a 350 crank in the 305 and it will vibrate apart

 

they share the same crank and connecting rods as long as you get a one piece rms crank from an 87 to 91 motor you should be fine the only difference is in the harmonic balancer and flex plate if you can reuse the old ones that would be perfect.

 

Very true. It is easier to put a 305 crank in a 350, than to put a 350 crank in a 305. The 350 crank is heavier. Good luck on you search.

 

yup
